Dec. 6, 1960 jy-l C. l. WILLIAMS FLEXIBLE SOCKET Filed Aug. 5, 1954 v vwv\ Z nited States This invention relates to concrete forms and moreparticularly it relates to an improved waler rod bracket constructionused in the erection of concrete forms of the cantilever type `asdisclosed in my co-pending U.S. application, Serial No. 233,853, tiledJune 27, 1951, for Method and Apparatus for Handling Forms, now UnitedStates Patent No. 2,825,115 granted March 4, 1958, and also in my U.S.application, Serial No. 323,528, led December 2, 1952 for CantileverForm, and isa particular improvement over my co-pending U.S.application, Serial No. 344,271, filed March 24, 1953, for Waler RodBracket and now abandoned, and which also incorporates certain featuresas disclosed and claimed in my U.S. Patent No. 2,659,125 grantedNovember 17, 1953, for Clamp Bracket. A

The invention is particularly directed to the improvement in a cla-mp`bracket for mounting a waler rod or she-bolt construction for assemblyto a cantilever-type form construction with strongbacks, such as areused on concrete forms in the forming of huge blocks of concrete thatlare poured in dams, and the forms therefor may be erected in Ia minimumof time and with a minimum Iamount of equipment.

Prior to my invention, waler rod brackets used in the erection ofshe-bolts permitted the threaded free end of the she-bolt extendingoutwardly beyond the form to become bent and/or further damaged becauseof the buckets of concrete, as they are'lifted, coming in contact withthe waler rod bracket members. In addition, `as the buckets of concreteare raised, considerable spillage occurs on the forms and some of theconcrete piles up on the waler rod clamp brackets so that at timesbefore the forms can be disassembled, it is necessary to chip away theconcrete which is set about the threads and nuts of the waler bracketand she-bolts. Also, with the waler rod bracket as disclosed and claimedin my aforementioned co-pending and now abandoned application, SerialNo. 344,271, it was impossible to provide suicient angular adjustmentfor adjusting the forms for angular or battered faces, such as requiredon dams, retaining walls, and the like.

It is, therefore, a principal object of my invention to provide animproved waler rod bracket construction to prevent bucket damage to theshe-bolts where they extend through the clamp brackets and spillage ofconcrete upon the free ends of the she bolts.

Another object of the invention is to provide an irnproved clamp bracketin which the outer threaded end of the she-bolt is enclosed, and theelongated tubular portion of the clamp bracket enclosing the she-bolt isrecessed within the strongback.

Another object of the invention is to provide an irnproved clamp bracketwhich may be used on any standard form of threaded she-bolt or waler rodconstruction irrespective of whether the clamp bracket is applied to thestrongback of a cantilever type form or to the split waler constructionfor use in concrete forms of lighter constructions.

atent O Still another object of the invention is to provide an improvedwaler rod bracket of the enclosed type and also permit adjustment of theshe-bolt and its elongated tubular adjusting nut therefor exteriorly ofthe enclosure therefor.

Still another object of the invention is to provide a clamp bracketconstruction also adapted for use on waler rods or she-bolts which pullout of the concrete or disconnect back from the surface of the concrete.

Another object of the invention is to provide an improved waler rodbracket which may be readily assembled to a strongback oi a cantileverform, for example, with a minimum amount of drilling the strongback forreceiving the she-bolts and a contiguous portion of the clamp bracket.

Still another object of the invention is the provisionof improvedfastening devices which are adapted to secure either cantilever typeforms to cast concrete, and also are adapted to secure oppositelydisposed form members together by means operable to the exterior of theforms and which are shielded.

Another object of the invention is to provide a simple form of anelongated tubular adjusting nut as a shield for conventional she-boltsor waler rods.

Another object of the invention is the provision of improved fasteningdevices so that oppositely positioned concrete form members may bespaced in their opposite position by manipulation of the devices fromthe outside of the form.

A further object of the invention is to provide a clamping devicecomprising an elongated tubular adjusting nut operatively mounted on theouter end of the waler rod and a clamping bracket complementally formedthereto to detachably receive the tubular adjusting nut.

A further object of the invention is to provide an elongated tubularadjusting nut for threadably receiving a she-bolt 'at one end andprovided with operator-operated means Aat the opposite ends foradjusting the tubular adjusting nut axially with respect to theshe-bolt, and also to provide a closure for the open end of the tubularadjusting nut to receive a wrench for adjusting the shebolt.

Still another object of the invention is to provide a clamp brackethaving -an elongated slot to complementally receive an elongated tubularadjusting nut of a clamping device, and to permit angular adjustment ofthe tubular adjusting nut with respect to the face of the clampingbracket.

Still another object of the invention is the use of the improved walerrod brackets in concrete form construction utilizing dummy she-bolts andpigtail anchoring means.

The invention also has `among its objects the production of improvedfastening devices of the kind described, which are simple inconstruction, reliable, durable, economical, inexpensive, easilyinstalled, rand satisfactory for its pur-pose.

In order to accomplish the various objects of the invention, I haveprovided an improved fastening device or waler rod bracket incorporatingshielding means for the free threaded adjusting end of a she-boit orwaler rod, and it may also provide a shieding means for the adjustableor iloating nut if the elongated tubular shielding means is fabricatedwith an adjustable or floating nut rather than incorporating anintegrally threaded portion. The improved elongated tubular shieldingmeans and complementally formed clamping bracket are formed as separablemembers though it is within the scope of the invention that an elongatedtubular shield may be applied to a conventional clamping bracket orwaler rod bracket, and in which the adjusting nut and the adjustableshebolt may be adjusted exteriorly by the insertion of suitable wrenchesthrough the shielding means. It is, therefore, within the scope of theinvention that the elongated tubular shield may be formed with anadjusting nut construction for the she-bolt as disclosed and claimed inthe aforesaid co-pending and now abandoned application, Serial No.344,271. It is, however, preferred to form the shield for the she-boltor tie rod as an elongated tubular member threaded at one end tocomplementally and adjustably receive the threaded end of the she-bolt,and in which the opposite end is formed with operator-operated means inthe form of a handle for adjusting the shield in the form of anelongated tubular adjusting nut operatively mounted on the outer end ofthe waler rod. The clamping device also comprises a clamping bracketcomplementally formed to detachably receive the tubular adjusting nut inan elongated slotted opening to provide for angular adjustment of theclamping bracket with respect to the axis of the elongated tubularadjusting nut. If it is desired to form the elongated tubular adjustingnut in which a nut is flexibly mounted at the inner end of the tubularshield, it is an additional advantage since, in general use,occasionally the forms may have a slight batter or it is necessary toposition the waler rods or tie rods through the forms at a slight angle.

Many other objects and advantages of the construction herein shown anddescribed will be obvious to those skilled in the art from thedisclosure herein given.

To this end, my invention consists in the novel construction,arrangement, and combination of parts herein shown and described, andmore particularly pointed out in the claims.

Referring now to the accompanying drawing forming part of thespecification:

Fig. 2 is an enlarged view in side elevation, partly in section, of theimproved clamp bracket or waler rod bracket of Fig. 1, illustrating theconstruction of the shielding means forming the adjusting nur` and theshield for the outer end of the she-bolt together with itscomplementally formed clamping bracket to provide angular adjustment ofthe shielding means with respect to the clamping bracket; and,

Fig. 3 is a front elevational view of the improved clamping device of myinvention, illustrating the clamping bracket and the handle and shieldfor the elongated tubular adjusting nut.

Referring now more particularly to the drawing, an improved form ofwaler rod bracket S is shown as part of an improved waler rod, she-boltconstruction form tie rod, orV fastening device 6, and shown afxed tostudding or strongback 7 of a conventional concrete form construction 8of the tvne as illustrated in either of rnv cri-wending applications,Serial No. 233,853, led June 27, 1951, now United States Patent No.2,825,115 granted March 4, 1958; and Serial No. 323,528, tiled December2, 1952. As used in the claims, form tie rod may be considered as ageneric term to waler rod, she-bolt construction, or other form offastening device. The concrete form construction is conventionallyformed by a plurality of sheathing or planking 7 alhxed to thestrongback 7, or it may be erected as illustrated in my U.S. Patent No.2,659,125 granted November 17, 1953 by a plurality of oppositelypositioned form members, the boards of each form being connected bynails or the like with the vertically extending studs and, in thisinstance, the studs being connected by longitudinally extending walermembers. More particularly, however, the waler rod bracket of thisinvention is adapted for assembly to a she-bolt 9 which, in turn, isthreadably connected to a pigtail anchoring device 1t) which has beenprecast in concrete, forming the concrete construction to which thecantilever-type form 8 is assembled.

The form to which the improved waler rod bracket of my invention may beutilized may be of any desired length and height, and the oppositelypositioned form members when erected in this manner are adapted to bedismantled and used repeatedly for pouring concrete walls or massconcrete of the same or diierent thickness, and the forms may be usedeither for the construction of vertical or battered walls. The improvedclamping device 5 comprising a clamping bracket 11 and an elongatedtubular adjusting nut 12, however, is more particularly adapted for usewith the cantilever-type form construction in which the forms includethe relatively large strongbacks, which may vary in size up to twelveinches by twelve inches, and the sheathing 7 is made up of planking fourinches in thickness.

The cantilever forms of this type are preferably erected as disclosed inmy co-pending application, Serial No. 233,853, led June 27, 1951, nowUnited States Patent No. 2,825,115 granted March 4, 1958, by using adummy she-bolt construction as disclosed and claimed in another of myco-pending applications, Serial No. 233,851, filed .Tune 27, 1951, nowUnited States Patent No. 2,823,441 granted February 18, 1958, whichprovides an enlarged tapered opening 13 to receive the regular she-boltconstruction 9 which is assembled to the pigtail anchoring means 10which has been precast in the concrete block. After the cantilever formconstruction has been mounted upon the regular she-bolts, it may besuitably adjusted and leveled with a leveling jack 14 after theelongated tubular adjusting nut 12 of the clamping device 5 has beenassembled to the threaded outer end 15 of the she-bolt. To permit easein mounting, the waler rod brackets or clamping brackets 11, which arerelatively large in size and for use with the cantilever-typeconstruction of this size, are substantially eight inches square orlarger depending upon the size of the she-bolt with which it is used. Acounterbore 16 is formed in the strongback 7 to receive the elongatedtubular housing 12, and is slightly larger in diameter than theelongated tubular housing and is slightly greater in depth asillustrated in Fig. 1 to permit ease of insertion of the elongatedtubular housing within its counterbore, and to provide for slightadjustment for the she-bolt 9 to extend through its complementallyformed bore 17 in the strongback and a similarly formed bore 13 throughthe sheathing p'anking 7 as illustrated in Fig. 1. Although thestrongbacks as used with the cantilever construction are large timbers,nevertheless, the

ydrilling of the holes to receive the waler rods, which in constructionsof this type are one and one-fourth inches or one and three-eighthinches in diameter, reduces the strength of the strongback as do thecounterbores 16 which are also relatively larger in proportion than thediameter of the she-bolts since the tubular housings receive thethreaded end of the she-bolt 1S to shield it. It is, therefore, equallyimportant that any counterboring done to receive the tubular housing 12to protect the end of the waler rod must not be too great toadditionally weaken the strongback, as the pressures which these formswithstand from the fluid concrete before setting is relatively great,since the entire form is supported by the pigtail anchoring means andits associated she-bolt being held in place by the waler rod bracket andits adjusting nut affixed to the she-bolt.

Referring to Figs. l, 2, and 3, the principal feature of my improvedclamping device S is in the elongated tubular adjusting nut 12 whichreceives the threaded end 15 of the she-bolt 6 and, in turn, iscomplementally formed to an elongated slot 19 also angularly shaped asat 2t) and to the angle of the reinforcing rib 20' to provide forangular adjustments up to substantially 45 for the battered faces of thedams or retaining walls and the like. The shielding means 12 is soformed as to fully enclose the outer free adjusting end 15 of theshe-bolt within a bore 21, slightly larger than the outside diameter ofthe she-bolt. The shielding means is formed with a threaded bore 22complementally formed to the threaded end 15 so that the shielding meansis in the form of an elongated tubular adjusting nut operatively mountedfor axial adjustment on the outer threaded end of the waler rod. It ispreferred to form the tubular adjusting nut as a forging or malleableiron casting and the like, which has welded or aflxed thereto anoperator-operated means in the form of a handle construction 23. In theembodiment as illustrated in Figs. 1 through 3, the handle construction23 is afxed to the tubular shield construction 12 by an annular weld 24.The handle construction is provided with diametrically extending handleportions 25 affixed to an annular portion 26, having a hole 27 inalignment with the bore 21 of the adjusting nut 12. A closure 28 formedas illustrated in Figs. 2 and 3 closes the opening 27, and the closureis pivo.ally mounted by a bolt 29 affixed to the annular portion 26.When the handle is adjusted to the position as shown in Figs. 2 and 3,the closure is gravity actuated to overlie the opening to the tubularadjusting nut. If the handle is in any other position, it is within thescope of the invention that the bolt 29 may be secured to alix the coverin its proper position after the tubular adjusting nut has beencorrectly positioned with respect to the she-bolt 9 and the she-bolt, inturn, then properly aiiixed to the pigtail anchor construction 10. Thebore 21 and hole 27, which are in axial alignment, are also of adiameter to permit the insertion of a socket wrench therein to beattached `to the squared end 30 of the she-bolt for aixing the threadedopening (not shown) to a complementally threaded end 31 of the pigtailanchor for detachably aixing and removing the she-bolt to itscorresponding pigtail anchor. The clamp bracket or waler rod bracket 11may then be axed in place by suitably adjusting the elongated tubularadjusting nut 12 to rigidly aiix the bracket 5 to the outer face'of thestrongback.

In order to reduce the amount which the clamping bracket 11 extends infront of the face of the strongback, the clamping bracket is constructedas shallow as possible and is reinforced with angular ribs 32, Fig. 3.In order to provide for angular adjustment of the elongated tubularadjusting nut 12 with respect to the face 33 of the clamping bracket,spaced inclined ribs 34 are formed as illustrated in Figs. 2 and 3 alongthe longitudinal edges of the elongated slot 19. The ribs 34 arecomplementally formed to the annular portion 26 of the handleconstruction to be supported on the face of the ribs 34 in the 90position of the tubular adjusting nut, as shown in Fig. 2, or in any ofits angular adjusted positions between its `vertical position and itsmaximum adjusted position abutting the inclined portion and 20 so thatapproximately a maximum of 45 adjustment may be had. The handles arealso formed as thin as possible in cross section to maintain suhcientrigidity so that they may be used as handles for adjusting the nut andalso to be tapped by a suitable instrument, such as a hammer or maul, toits final adjusted position or for loosening. Also, the handles may beso shaped that a short piece of pipe may be placed over each end foradjusting the tubular adjusting nut.

Although the waler rod bracket is preferably for use with strongbacks inerecting a concrete form, it is also within the scope of the inventionthat the clamping device of this invention is equally adapted for usewith what is known as a split waler construction wherein the walers arepreferably two-by-fours or other suitable timbers between which theshe-bolt extends. In a construction of this character, the tubularadjusting nut 12 would be posi-tioned between the waler members and, ifnecessary, securing means, such as screws or doubleheaded nails 35, mayextend through the openings 36 in the ange 37 to secure the waler rodbracket in position on the waler members or in position to thestrongback, as shown in Fig. 1, so that the slotted opening 19 is inalignment with the counterbore 16 of the strongback. Likewise, althoughunnecessary in the cantilever-type form as illustrated in Fig. 1, as thepressure applied to the waler rod brackets is very great, Vthere 'isrelatively no need to ax the brackets in place on the strongbacks exceptif it is desired to secure them in place when the forms are dismantledor in moving the forms from one lift position to another. Although i. ispreferred to use a waler rod bracket of this type with a regularshe-bolt in erecting the forms, it is to be understood that it is withinthe scope of this invention that this type of waler rod bracket orclamping device is equally adapted for use with a dummy she-boltconstruction as disclosed in my aforementioned co-pending application,Serial No. 233,851, led June 27, 1951, now United States Patent No.2,823,441, granted February 18, 1958, and, in such case, the tubularadjusting nut and its complementally formed dummy she-bolt would bethreaded to correspond to the diierence in size between a dummy she-boltand a regular she-bolt, such as illustrated in Figs. 1 and 2.

Referring to Fig. 1, the leveling jack 1'4 has been conventionallyillustrated without the use of a protective covering. It is to beunderstood, however, that the waler rod construction as disclosed andclaimed in the copending and now abandoned application, Serial No.344,271, and which is shown in the dotted construction 3S, Fig. 1, isequally adapted for use in shielding the free end of the leveling jackas illustrated. When used in this manner, the hole for the leveling jackscrew is suitably counterbored as when the tubular adjusting nut andclamping bracket is used for protecting the free end of the she-bolt, ifit should `be desired to apply a clamping device and she-boltconstruction at the position of the leveling jack. Furthermore, it wouldbe preferable to secure the shielding waler rod bracket 38 with suitablesecuring means, such as screws or double-headed nails as described, withthe clamping device of Fig. 1 extending through lugs 39. With a levelingjack of the type illustrated, it is unnecessary to use the adjusting nutsuch as disclosed in the aforementioned co-pending and now abandonedapplication, Serial No. 344,271, although it may be used, if desired,for additionally locking the adjusting screw 14 in position. Otherwise,when used as a shield for the leveling jack, the adjusting nut may beadmitted and the adjusting screw of the jack extends through an openingin the boss of the bracket.

It is also to be understood that the clamping device or waler rodbracket construction of this invention may be used instead of the`mounting for the dummy she-bolt as disclosed in the aforementionedapplication, Serial No. 233,853, led June 27, 1951, now United StatesPatent No. 2,825,115, granted March 4, 1958. However, when used in thismanner, the outer end of the dummy she-bolt will necessarily have to bethreaded as is the regular she-bolt 9 with which this waler rod bracketconstruction is disclosed. When used in this manner, it is within thescope of the invention that the free end of not only the regularshe-bolt is protected from bucket damage but equally protected are theouter end of the dummy she-bolt and the outer end of the adjusting screwof the leveling jack. In addition, to avoid bucket damage to the freeends of the various adjusting members of a concrete form construction,any spillage of concrete, as it is being raised in buckets to be poured,is prevented from collecting on the outer ends of the adjusting membersof the she-bolts and leveling jacks so that, as it hardens, undue lossof time is not required in removing the set concrete from these membersbefore they may be detached either in removing the forms or removingthem to be raised into another adjusted position for pouring.

The outer contour of the shielding waler rod bracket 38 for the levelingjack screw 14 is preferably a modied dome or frustum of a cone to permitthe edge of the bucket as it is raised alongside of the form to slidefreely across the surface of the bracket so that the bucket is nottilted to any great extent to spill the concrete, and also to preventthe bucket from being caught on the bracket and cause damage to theform. Although the improved lform ,of clamping device including Atheclamping bracket 11 and its complementally formed elongated tubularadjusting nut 12 as it extends through the bracket with the attached`handles 25 extend beyond the outer face'of "thest-rongback,nevertheless, the silhouette is less in height than the shielding walerrod bracket 38. Likewise, the clamping bracket 11 is provided with theangular-shaped ribs 32 which tend to allow any bucket to pass over thesurface of the bracket, and the length and shape of the handles thereofare such as to prevent catching of the bucket so that it is not tiltedto any great extent to spill the concrete, and also to prevent thebucket from being caught on the bracket and handles and cause damage tothe form. It is to be understood 'that any other suitable shape for thebracket and the handle is within the scope of the invention, which willfreely allow a bucket to pass over the surface of the bracket and thehandle so that the edge of the bucket does not catch the bracket,causing 4the form to become misaligned or any damage to the free ends ofthe handle and to the free end of the she-bolt to prevent their removalupon dismantling the form. It is also to be understood that the overallprojection of the waler rod bracket should not be too great so that theoverhang of the bracket will cause a bucket to snag. For example, in theembodiment of the shielding bracket 38 for a twelve inch strongback, thedia-meter of this bracket is eleven inches and the height of the bracketis substantially three and three-fourths inches. From an inspection ofFig. l, it is noticed that the silhouette of the improved clampingdevice of Fig. 1 is less than the shielding bracket 38.

Although it is preferred to construct the elongated tubular adjustingnut 12 with the thread therefor tapped in the end of the housing, it iswithin the scope -of the invention'that the tubular housing 12 may beconstructed to receive a nut construction as disclosed and claimed inthe aforementioned co-pending and now abandoned application, Serial No.344,271. When constructed in this manner, the tubular housing 12 will beof such a size that the diameter of the bore 21 shall be equal to thatof the outside diameter of a hex nut for the she-bolt 4to be receivedwithin the bore with additional clearance to receive a socket wrench forthe nut. However, it is preferred to construct the elongated tubular nut12 as illustrated in order to reduce the size of the counterbore 16required in the strongback so as not to greatly reduce Vthe strength ofthe strongback. lt is also to be understood that the threaded portion ofthe tubular nut 12 may ybe rfabricated by a separate nut integrally castwithin the inner end of the housing rather than being drilled andthreaded, or any other method of securing a nut may be used so that incase of excessive wear of the threads, it is only necessary to replacethe nut rather than the elongated tubular housing structure. Althoughthe construction of the nut for the she-bolt as disclosed with respectto the aforementioned co-pending and now abandoned application, SerialNo. 344,271, permits the floating of the nut and she-bolt connectedthereto so that the bracket may be moved to slight angles, in thepreferred construction of this invention, this angularity isaccomplished by means of the slotted opening 19 together with theinclined ribs 34 and the annular portion 2'6 of elongated tubularhousing which rides on the faces of the ribs 34. Therefore, when theforms are constructed with a slight batter or the waler rods areinserted at a slight angle, the face of the bracket 11 still sets flushwith the waler members or the face of the strongback to which it isaixed.

It is'preferred that the threaded opening 22 shall be tappedto receivethe conventional 8-pitch Acme thread 15 of the waler rod as shownschematically in Fig. 2. it is alsopreferred that if instead of thethreaded opening 22, nuts are used as disclosed in the aforementionedcopending and now abandoned application, Serial No. 344,271, the nutsshall also be tapped to receive the conventional8-pitcii-threadusedgforwalerLrods. `it is .also

preferred that the nut should Ibe formed hex-shapedso that they may bereadily actuated with a suitable vwrench inserted within the bore 21. Itis also preferredto form the nuts from steel and the elongated tubularnut 12 also from steel or malleable iron, and the castings for thebrackets 11 and 38 from steel or malleable castings or from any suitablematerial either cast or forged to give the requisite strength for anypurpose they are used. It is' also preferred that the end of the rodshall be formed with a squared head 30'or other suitable head in orderto provide suitable means for adjusting the she-bolt 9.

The improved clamping device including the clamping- 'bracket' 11 andelongated tubular adjusting nut have an advantage over' the conventionalnut units which are shaped as washer-like casters for rotation againstthe waler. With the conventional construction, it is difcult to turnmetal upon wood under Ythe normal high pressure that is had in concreteform work. However, with this improved elongated tubular adjustable nutand bracket therefor, the elongated tubular nut which, when beingassembled to an integrally cast pigtail anchor 10, would normally havethe she-bolt 9 assembled to the tubular nut and after the forms havebeen assembled, the clamping bracket 11 is generally aixed in place withthe securing means 35 so that one would insert the elongated tubular nut12 and the she-bolt in place through the elongated slot 19 and attachthe threaded tapered end of the she-bolt to the complementally threadedportion 31 of the pigtail anchor. There is usually enough frictionbetween these threads of the elongated tubular nut 12 and a thread 15 ofthe she-bolt so that, for a few turns, the she-bolt may be attached tothe threads 31 of the pigtail anchor by rotating the she-bolt in theproper direction by the handles 25 of the tubular nut. `After theshe-bolt is caught, a wrench is inserted within the bore 21 after thecover 28 has been opened and attached to the squared end 30, whereuponthe she-bolt may be suitably aixed and tightened by the wrench. Uponremoval of the wrench, the nut 12 may be rotated until it comes incontact with the clamping bracket 11 with the inner face of vthe annularportion 26 of the nut abutting the face of the ribs 34, either asillustrated in Figs. 1 and 2 or at any regular position which theshe-bolt may take. The adjusting nut 12 may be securely atlxed bytapping the handles 25 with a suitable mallet or using a short length ofpipe until the form is securely aixed to a face of the precast slab ofconcrete as illustrated in Fig. 1 in which the pigtail anchor is aixed.She-bolt constructions together with the clamping device of thisinvention may also be assembled to pigtail anchors at the upper part ofthe strongback prior to the pouring of the next lift. After the concretehas set, the lower she-bolt is detached in the reverse order asdescribed in reference to Fig. l, and the upper she-bolt is alsodetached and the forms raised for pouring the next lift. It is to beunderstood that the upper she-bolt construction together with theclamping device may be in the form of a dummy she-bolt construction.

The she-bolt is of larger diameter, forming an enlarged tapered opening13 in which a regular she-bolt may be positioned with greater ease atthe time of securing the cantilever form in its next raised position tothe precast and set concrete.

It is preferred to form the clamping bracket 11 either as a casting orforging in the shape as shown in Fig. 3. Although it is preferred to besomewhat rectangular in shape, it may be square or any otherconventional geometric form, though the shape as illustrated ispreferred in View of the elongated slot 19. The greater bearing surfaceof the bracket .as illustrated is desirable in the use of the clampbracket because of the extreme pressure used by the lateral thrust ofthe poured concrete against the cantilever form. Nail or screw holes 36in the ange 37 permit the fastening of the clamping bracket 11 t0 thestudding or .strongback 7, although withthis type of assenso Y"bracketthere is no need to use the additional securing means except perhaps inthe split waler structures or as, `in this case, where the longitudinalslot is used to permit angular adjustment for battered surfaces. Thefastening of the clamping brackets 11, as illustrated in Fig. 1, issometimes advantageous in that the she-bolt and its tubular adjustingnut 12 may be unscrewed or detached from the concrete and the bracketremains in place, and the nut and she-bolts are then reinserted.

In constructing a concrete form, using the improved waler rodconstruction including the elongated tubular adjusting nut and clampingbracket of the embodiment illustrated in Figs. 1 through 3, the studdingor strongback and sheathing are drilled to receive the she-boltconstruction 9, and the strongback is counterbored to receive thetubular adjusting nut 12. Each securing device or waler rod assembly isthen erected as shown Iin Fig. 1 in accordance with the disclosure of mycopending application, Serial No. 233,853, filed lune 27, `1951, nowUnited States Patent No. 2,825,115 granted '-March 4, 1958; and, ifdesired, the use of a dummy shebolt construction as also disclosed in myco-pending application, Serial No. 233,851, filed June 27, 1951, nowUnited States Patent No. 2,823,441 granted February 18, v195 8, may alsobe used in conjunction with the improved waler rod bracket constructionof this invention. In the construction illustrated in Fig. l, after theform is assembled in place and supported by the pigtail anchoring means,the she-bolts 9 are suitably adjusted using the squared end 30, andafterwards are locked in place with Athe elongated locking nut 12. Theelongated tubular housing 12 and its complementally formed recess 19permit any slight angularlity necessary for the erection 4of theshe-bolts to any associated anchoring means or tie rod, whether the tierods or anchoring means are .placed in a horizontal position or at anangle.

Forms constructed with the waler rod brackets and tubular adjusting nutof this invention may be raised and relocated at will, as is wellunderstood in the art. When it is necessary to remove the forms, theadjusting ,nuts 12 are loosened by suitable tapping on the handle with amallet or using a pipe to unscrew the nut a slight amount, after whichthe she-bolts 9 may be detached from the pigtail anchoring means 10 orother securing device by unscrewing the she-bolt with a suitable wrench.attached to the squared end 30. The clamping device lincluding theclamping bracket and tubular adjusting nut of this invention is,likewise, equally adaptable for use with the constructions oftheaforementioned applications. The forms, when dismantled, may then bereassembled wherever desired in the reverse order.

It is thus obvious that there has been disclosed a simple andinexpensive form of an improved adjusting nut and clamping brackettherefor, for use with the conventional form of she-bolt construction asillustrated, which may be readily assembled and disassembled intheconstruction of concrete forms.

There has also been disclosed an improved elongated tubular adjustingnut which serves as a shield to prevent damage to the outer end of theshe-bolt since the tubular adjusting nut and outer end of the she-boltare embedded Within the strongback or between the split walerconstruction to prevent damage by the concrete buckets, and alsoshielding the outer end of the she-bolt from the spillage of concreteacross the face of the form, and an additional shield being provided yby`a cover 28 at the outer end of the bore within which the outer end of'the she-bolt is axially positioned. Although it is preferred to formthe clamping bracket and tubular adjusting nut as separate members toprovide for angular adjustment, it is also to be understood that theclamping bracket and tubular adjusting nut may be formed as one piece,if no angular adjustment is desired or if a exible nut is used insteadof the tapped hole22. It is also understood that it is within the scopeof the invention that the tubular adjusting nut12 may be used withoutits closure or shield 28, and also that the improved clamping device ofthis construction may be used separately or in conjunction with otherforms of clamping devices. Furthermore, the construction may be adaptedfor waler rods already in use in the eld which may have conventionalU.S. threads, Acme 4, 5, or 8-pitch threads, or other suitable threads.

Furthermore, the improved waler rod clamping device of this inventionworks equally well on vertical or battered walls. 'Ihe she-bolts andadjusting nuts are easily demounted and no wrecking is necessary, thuspermitting greater salvage of lumber.

Having thus described my invention, it is obvious that variousimmaterial modiiications may be made in the same without departing fromthe spirit of my invention; hence, I do not Wish to be understood aslimiting myself to the exact form, construction, arrangement andcornbination of parts herein shown and described, or uses mentioned.
